We have 500 grams of a 10% salt solution. How many grams of water must be added to dulite the solution to form a 4% solution. Sh
lys-0071 [83]
Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add

50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750

750 grams of water

First you had to add by seven from both sides of equation form.

-7+\frac{f}{2}+7=-1+7

Then simplify by equation.

\frac{f}{2}=6

Next, you multiply by two from both sides of equation form.

\frac{2f}{2}=6*2

And finally, simplify by equation.

6*2=12

2*6=12

12/6=2

12/2=6

f=12

Final answer: \boxed{f=12}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

The value of the square root of 82 is between which two integers?
zaharov [31]
The answer: 9 and 10 or 8 and 9
8x8=64
9x9=81
10x10=100
They are close by 18 so If it’s only an answer I would go for 8 and 9
